sake-10f illustration, Fig. 3 is a plan view of the apparatuswith thetop. open, Fig. 4: is a perspective view ofa switch mechanism, and, Fig.5 is a diagrammatic view'of the circuit. I r

'In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 10 designates apreferably rectangular shell or casing, which may be preferably formedof I 1 wood, as shown, while the same may be formed of other suitablematerial such as sheet metal or'theilike. The forward end andt't'o'p.of'the casing lOYare formed open, and are normally covered by verticaland horizontal doors '11 and 12. The vertical door 11 is'hinged at itslower end,1as shown at 18, with the floor 'orbottom of the casing '10,"whereby the same is adapted to be swung in a vertical planewithrelation to :suchca sing. The'vertical doorl'l may be retained orlocked in a vertical closed position by'a detachable latch 14 or thelike.

The horizontal door" 12, is hinged at its forward-endas'shown at 15, tothe upper Iendof the "vertical door 11, and is adapted I to swing in avertical plane with relation thereto. "door 12'is securedor locked tothe cor- The .rear' end of the horizontal responding "end" of the casing10 by a latch 16. or the like, :as more clearly shown in Fig. 2; Forconvenience *a handle 17 is preferably attached to the upper surface ofthe -hori'z ontal'door .12', so that the appara- The ver- 'Ar'rangedwithinthe casing 10. is a horiinner surface highly polished. Thereflector-shell 20 is provided in its lower portionfwithan opening '21,receiving a socket 'member QQ, 'of-fan eleotricla mp or bulb 23.

The socket member'QQ, as'is customary, is

formant porcelain orotheriinsulatingmaterial, ?is vertically "arranged,.and rigidly secured to fthe floor or bottom of the casing 10, The blilbor lamp 23 isvertically ar ranged within the rear portion of thereflector casing20, as shown. The lamp 23 will, in some instances, bereferred to in the claims as an interior lamp or source of light.

The numeral 24- designates an exterior electric lamp, bulb, or source oflight, which is rigidl attached to the forward end of the horizontaldoor 12, adjacent the hinges 15, as shown. This exterior lamp is ofgreater resistance than the interior lamp 23 and is connected in seriestherewith, as willthe eggs or the like, and upon inserting an egg orwithin the egg receiving opening or openings, whereby the circuitclosing door or doors 19 are swung inwardly, the exterior lamp is cutout of circuit or extinguished, while the interior lamp 23 is approximately simultaneously made to glow, by the cutting out of circuitof the higher resistance of the exterior lamp, and the 010s ing of theinterior lamp circuit.

As more clearly shown in Figsp l and 5, the numeral 25 designates asource of current, having its positive pole connected with a wire 26,which is connected with a preferably rectangular bus bar 27, securedupon an insulating or fiber plate 28, rigidly attached to the innersurface of the vertical door 11 adjacent the upper end thereof. The ends29 0f this bus bar are L-shaped, as more clearly illustrated in Fig. 2,whereby the longitudinal portion 30 of the bus bar (see Fig. 2) isspaced a substantial distance from the inner surface of the verticaldoor 11. Attached to the longitudinal portion 30 of the bus bar arespring contacts 31 and 32, adapted to engage with the circuit closingdoors 19, when the latter are swung inwardly. Each of these circuitclosing doors embodies a metallic head 33, upon the outer surface ofwhich is secured an insulating pad or cover 34:, of the proper size toenter the opening 18, the same being preferably formed of asbestos orother fibrous material. A metallic strip 35 is rigidly secured to eachmetallic head 33, and has an electrical hinged or pivot connection witha co-acting stationary bus bar 36, secured to the insulating strip 28,as shown. Each of the circuit closing doors 19 is retained closed andreturned to the closed position when moved therefrom by a spring 37, asshown. Connected with the bus bar 27 is a wire 38, having the exteriorlamp 24 connected in series therewith. The end of the Wire 38 isconnected with a stationary contact 39 so cured to the inner side of thevertical door 11, and having no direct electrical connection with thebus bars. The stationary contact 39 is arranged adjacent and in the pathof travel of one of the circuit closing doors 19, and normally haselectrical engagement or connection therewith. Connected with the busbar 36 is a wire 40, having the interior lamp 23 connected in seriestherewith, the wire 40 being connected with the opposite pole of thesource of current 25, as shown.

The operation of the apparatus is as follows :1Vith the parts arrangedin their operative positions, as shown in Figs. 1 and 2, a circuit isclosed for causing the exterior lamp 24: to glow, while the interiorlamp 23 does not perceptibly glow, it being understood that both thecircuit closing doors 19 are in the closed position, whereby they haveno electrical engagement with the contact springs 32. In this closedcircuit current flows from the positive pole of the source of current25, through wire 26, a portion of bus bars'27, wire 38, exterior lamp 21, a portion of wire 38, stationary contact 39, the adjacent door 19,bus bar 36, wire 4:0, in terior lamp 23, and back to the opposite poleof the source of current. As the lamp 2 1 has a higher resistance thanthe lamp 23 and both of these lamps are connected in series, the currentis cut down by the lamp 24, whereby suflicient current does not pass tothe lamp 23 to cause the same to perccp tiblv glow.

When an egg is inserted in the receiving opening at the left, thecorresponding closing circuit door 19 is swung inwardly to electricallyengage the contact spring 32, (see Fig. 5) whereby the exterior lampwill be cut out of circuit, and a short circuit be completed, includingthe lamp 23, which is now made to glow. In this short circuit currentflows from the positive pole of the source of current, through wire 26,a por tion of the bus bar 27, spring contact 32, the adjacent contactclosing door 19, bus bar 36, wire 40, and through interior lamp 23 backto the opposite pole of the source of current.

When an egg is inserted in the egg re ceiving opening 18 to the right,the exterior lamp 24: is cut out of circuit and a short circuitcompleted, including the interior lamp 23. When the adjacent circuitclosing door 19 is swung inwardly the same breaks electrical engagementwith the static-nary contact 39, and makes electrical engagement withthe adjacent spring contact 31. Current in the short circuit for causingthe interior lamp 23 to glow, flows from the positive pole of the sourceof current 25. through wire 26, a portion of the bus bar 27, springcontact 31, the adjacent circuit closing door '19, bus bar 36, wire 40,and through the interior lamp 23 back to the source of current.

It is obvious if both circuit closing doors 19 are simultaneously swunginwardly, the exterior lamp 2st will be cut out of circuit, and theshort circuit completed to cause the interior lamp to glow.

While it is preferred to use the apparatus in a dark room, yet I havefound that some degree of success is obtainable by using the samewithout the dark room, in which event it is unnecessary to employ theexterior lamp 2%, the same being extinguished by manipulation of theordinary switch 2%.-

' It is to be understood that the form of my invention herewith shownand described is to be taken as a preferred example of the same, andthat various changes in the shape, size, and arrangement of parts may asresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
